means Afor supplying fuel to the engine from gi the equalized tanks; a boiler; and awater tank at each end of the locomotive, and an equalizing pipe connecting the two tanks with the boiler so thatas vthe weight due to the consumption of fuel and water becomes less, it willnot affect the even distribution ofthe weight onthe driving wheels .of the locomotive;

Y3. rEhe combination in a locomotive using an internal combustion engine, of two fuel oil tanks, one near each end of the locomotive; an equalizing pipe connecting the two tanks; and means for conveying the fuel oil from the tanks tothe cylinders of the engine, so that aS the weight of the fuel in the tanks becomes less due to'the consumption of the fuel, the weight will be distributed so as not to affect the operation ofthe electricmotors by which the locomotive is driven. y

at each'end of the locomotive; an equalizing pipe connecting the two tanks; anda pipe c leading from the equalizingpipe to a pump which forces the oil to a current supply tank and from `the current supply tank to the several cylinders of the engine, so that as the fuel oil is used the weight becomes less due tothe consumption of the fuel but the weight will not be shifted, it being evenly distributed so as not to affect the operation ofthe electric motors.
